Maybe, but I dont think that how they behave depends on that TNA exists.But I do like that there exists two big wrestling companies in USA. TNA should become bigger aswell, so that it can rival WWE, cause monopoly isnt good for anyone exept the company that has monopoly..

I don't think tna really changes how the wrestlers behave. They have to take a pay cut to change to tna and they could make just about as much money wrestling in the independents. Many fans don't understand that the wrestlers are not really treated with much respect in the wwe. Maybe a few of the top stars like Cena, Orton, The Undertaker and a few others get treated great, but most don't. Many wrestlers that are in it for the biggest pay day, put up with how they are treated. Those that really save their money or don't care so much about the money, decide that it's not worth it, so they do what it takes to get out of the wwe. But wrestlers also have the option of going to Japan, but many don't want to stay there. They can also make fairly good money in Mexico. So there are more options than just tna. I think guys like Kurt Angle would have just left wrestling if it wasn't for tna, rather than stay with the wwe.

But wrestlers NEED other options so they can get treated with the respect they deserve.
